In my opinion Witcher 2 is the most beautiful game ever released. It is the case of when technological superiority meets with excellent art style..the result is just spectacular. There is a thread on neogaf of high res screenshots - it is being flooded with screens from TW2 these days, and anyone can see how extremely beautiful this game looks.

CDP weren't kidding when they said they look better than DA2. They make DA2 look like game from 10 years ago.
